Hi all,
I agree with Simon's comments. Before our 2006 Grasswren Trip to Mt Isa I did a
lengthy Google search as well as going back over some historical texts I have
access to and came up with exactly the same comments.
More than once I found the suggestion that the bird is crepuscular or diurnal
rather than nocturnal.
Who knows but maybe now, with our crazy weather throwing up lots of unusual
sightings, it is the right time to do some serious searching. More than one
bird has been thought extinct/threatened rare until we learnt when and where to
look for it.
Yes, I am sure this bird is not at all common and finding it is like trying to
find a needle in an Australia-size haystack but wouldn't it be wonderful ....
So, how do we go about setting up a network to share knowledge and reduce the
size of he haystack?
